Works flawlessly with Python, MATLAB, C++, Excel, and C#. Cost: $0 (Open-source under the MIT license). REFPROP Mini (NIST’s Free Version)
Refprop 10 is a software package developed by the National Institute of Standards and Technology (NIST) to provide a comprehensive database of thermodynamic properties for refrigerants and other fluids. The software allows users to calculate properties such as density, viscosity, thermal conductivity, and heat capacity for a wide range of fluids. refprop 10 free download 2021
The National Institute of Standards and Technology (NIST) is a U.S. government agency responsible for developing and maintaining the REFPROP software and database. REFPROP is a commercial, copyrighted software product.
The Reference Fluid Thermodynamic and Transport Properties database (REFPROP), developed by the National Institute of Standards and Technology (NIST), is the industry standard for chemical and thermal engineering data. Because it is a proprietary, copyrighted software program, REFPROP Mini (NIST’s Free Version) Refprop 10 is
DWSIM is a full-featured, open-source Chemical Process Simulator for Windows, Linux, and macOS. It features a robust built-in property package evaluator (including Peng-Robinson, NRTL, and steam tables) that allows you to calculate fluid properties and simulate entire chemical plants for free. Conclusion
If you are setting up a project or simulation right now, I can help you get started with the legal alternatives. Let me know: : Includes 147 pure fluids
You lose access to official NIST patches, fluid updates, and integration wrappers.
REFPROP (Reference Fluid Thermodynamic and Transport Properties) is a widely used software library from the National Institute of Standards and Technology (NIST) that provides thermophysical properties (equations of state, transport properties, mixture models) for pure fluids and mixtures. REFPROP 10 is a major version released by NIST that includes updates to fluid models, mixture parameters, and software interfaces.
: Includes 147 pure fluids, 5 pseudo-pure fluids (like air), and supports mixtures with up to 20 components.
: It uses the same high-accuracy Helmholtz energy formulations as REFPROP for its primary fluids. 2. Cantera
